Purchase of new camera

by Photoforfun / January 21, 2013 11:19 AM PST

I like the colors of the photos from my iPhone 5 but since I have a child too many photos are blured because she moves. What would you suggest me to buy of a fast focusing camera and not too big. Thank you. Bjarne

Focusing is not the problem

Photography requires light. When there is not enough light, a camera either has to use a flash or reduce the shutter speed. In the case of your phone, it reduces the shutter speed. This would happen with a camera too if you do not use a flash. The only ways around not using flash and still getting a blur-free image is to raise the camera's digital sensor sensitivity, and/or use a wide aperture lens. Small cameras have small sensors, so when you raise the sensitivity, the photos become very "noisy," or grainy looking. Most small cameras do not have very wide aperture lenses either.

So...if you want to take photos indoors, get more lights in your house, or use the flash on the camera, or buy a larger camera with a bigger sensor and wider aperture lens.

Sony RX100 if you can afford it. Or Canon S100 or S110 if you can't afford the RX100.

Full disclosure: I own an RX100 - Mark

Thanks for your answer. The Sony RX100 is not too expensive, but I have red that since it has not phase detection autofocus it's a little slow in focusing and what I want is a fast focusing camera when you have a child. What do you think?
Best regards

The Sony is indeed a good choice for its type. It does not have phase detection AF, but its contrast detection AF is reportedly very fast. You can make it even faster by using technique of pre-focusing, or holding down the shutter button half-way to engage the auto-focus and exposure before taking the photo.

Some newer non-DSLR cameras offer phase detection AF in addition to contrast detection AF. The Nikon 1 cameras have such technology. Nikon 1 cameras use the same size sensor as the RX100, but the Nikons are interchangeable lens cameras. The upside of that is you can attach an appropriate lens for low light, landscape, macro, etc. The downsides are you can't have an all-in-one lens, and the whole package is physically larger.

I'd like to know more about "phase dectection."

I'd read face detection but phase? That's a new one. Tell more.

Nice. My old method

My background in video had us using the contrast and edges to focus.
